Xiaomi smartphones are famous for their performance, but even powerful hardware eventually begins to stumble on accumulated software debris. This is an inevitable process: every time you open a web page in Chrome or flip through a feed in Telegram, the device saves temporary files for faster download of content the next time you call.
However, when the size of this data reaches gigabytes, it stops speeding up and begins to slow down the MIUI system. Cache memory can take up up to 30% of available space, causing interface lags and quick battery discharge. In this article, we will discuss proven cleaning methods that will return your gadget to its former briskness.
Not only will you learn about standard Android tools, but the hidden features of the HyperOS and MIUI shell that users often ignore. Understanding how the system manages temporary files will help you keep your device in perfect condition without losing important data.
Why the cache is filling and how it affects Xiaomi
The caching mechanism in Android is designed to minimize the load on the processor and network. When you visit a site with heavy graphics, the browser stores pictures and scripts in local storage. When you re-enter the resource, the system reads data from the fast drive, rather than downloading them again from the Internet.
The problem arises when the cleaning algorithms fail to handle the amount of garbage, and in the MIUI shell, the situation is exacerbated by aggressive optimization of background processes, which sometimes “forgets” to delete old application files, which leads to the drive being filled with duplicates and broken links.
The symptoms of a crowded cache are easy to notice: pages in the browser open with errors, an outdated version of the site is displayed, and applications can fly out immediately after launch. If you notice that the phone is heating up even in standby mode, chances are that background services are constantly trying to write new data to a crowded memory sector.
⚠️ Before a large-scale cleaning, make sure you have up-to-date backups of important data.While clearing the cache is safe, accidental deletion of user data is possible with inattentive choice of options.
It is important to distinguish between app cache and browser cache: the first stores temporary program data (for example, YouTube video previews or messenger avatars), and the second stores exclusively web content. Clearing both types is necessary to comprehensively speed up Xiaomi’s work.
Cleaning cache with standard MIUI and HyperOS tools
Xiaomi’s shells have a powerful built-in maintenance tool, and it’s the easiest way to remove debris without installing third-party software.Cleanup scans the device for temporary files, ad residues, and unnecessary APK installers.
To start the process, look for the Security app on your desktop (the shield and lightning icon). Inside, select Cleanup. The system will automatically scan the memory and prompt you to remove the debris found. Press Clean to complete the procedure.
☑️ Quick cleaning checklist
However, standard cleaning often leaves the cache of individual applications intact, considering it important data. To get to the deep settings, go to Settings → Applications → All applications. Here you can manually manage the memory of each program.
Select a heavy app (like Instagram or Facebook) and look for Memory, where you will see two buttons: Clear cache and Clear all data. The first one is secure and only deletes temporary files, the second one resets the app to a state immediately after installation, removing logins and settings.
Deep Cache Cleaning in Chrome and Mi Browser
Web browsers are the main generators of temporary garbage on a smartphone. In Google Chrome, which is installed by default on many global versions of Xiaomi, cleaning is done through the settings menu. Click on the three dots in the upper right corner and select History.
In the menu that opens, click New tab or go straight to Settings → Privacy & Security → Clear history. Here, it is important to choose the right time range. For full cleaning, select All the time.
Make sure that the tick is on the item Images and other files saved in the cache. unchecking the "Browsing History" or "Cookies" will save your logins on the sites, removing only heavy graphical debris.
💡
Use Incognito mode to visit sites that do not require history, and in this mode, the cache is automatically deleted after the tab is closed, saving time for manual cleaning.
Mi Browser users (Xiaomi's standard browser) can take advantage of the built-in acceleration feature. In the bottom panel, click on the profile icon or three menu bars, then select Clear Data.This browser often accumulates (a large number) of banner ads that also take up space.
For advanced users, a hidden Chrome engine settings page is available. In the address bar, type the command:
chrome://clear-internal-sites-dataThis command allows you to clear the cache for the browser's internal pages, which sometimes helps correct rendering errors of complex web pages. After you complete the actions, restart the browser to apply the changes.
Using a Developer Mode for Forced Cleaning
Android has a hidden menu for developers that gives you access to more subtle system settings. To activate this mode on Xiaomi, go to Settings → About Phone and quickly click 7 times on the MIUI Version (or OS Version).
After activation, a new section will appear in the settings menu Additional → For developers. scroll down to the Apps block. Here you can find the option Do not save actions or settings for the background process limit, but we are interested in the Memory section.
Some firmware versions have a feature that forces all services to stop before cleaning, which is useful if the system is stuck and prevents files from being deleted through the standard interface, and you can see detailed statistics of memory usage by each process in real time.
⚠️ Warning: Be careful in the Developer menu, changing animation settings or process limits can cause system instability, only changing the settings you are sure of.
There is another method that involves the Warehouse section of the developer menu, where you click on a particular application to see not only the space you're occupying, but also the services you're running. Forced Media Storage or Download Manager to stop before clearing the cache helps you delete files that the system thought were "busy."
Automation of the process with scripts and applications
For those who prefer automation, there are software-cliner apps like SD Maid or Files by Google that run deeper than standard tools and can find "orphaned" files left over from deleting programs, but require special permissions on Xiaomi.
When you first run an application, MIUI will request permission to access it through Special App Access, without which the clog of other applications cannot be deleted automatically, and you will need to click on the link in the settings and allow the utility to work.
Alternatively, you can use a built-in task scheduler, and you can configure automation scenarios in the Security → Battery application, such as starting a garbage cleanup when you reach 100% charge or when you connect to Wi-Fi.
